Abstract
An antenna system () includes an antenna structure (), a receiver (), and an antenna system controller (). The antenna structure includes an arrangement of antennas (), a signal combiner (), and a switching matrix (). The arrangement of antennas is designed to have a set of antenna element separations that are optimized to provide lowest correlation coefficients of intercepted radio signals for a corresponding set of electromagnetic environment types that vary from a very low density scattering environment to a maximum density scattering environment. The antennas (), (), (), (), () in the antenna arrangement each include at least one element that has a common polarization. There is at least one antenna that is a dual polarized antenna. The antenna system selects an antenna element pair that corresponds to the environment type which it is operating and thereby receives a best combined signal.
